SHIP SAFETY DEVICE.

Application filed February 2:8, 1928.

This invention relates to a new and useful. ship safety deviceespecially adapted for the purpose of keeping a ship afloat during exxi-cine heavy or rough seas and for the purs pose of keeping; atouiulercd ship afloat.

The object oi? the invention is to provide a pair oi buoyant inflatablemembers adjustably secured to and extended from the sides of the shipand a means oi inflation in combiic nation with a means igidly holding;the said buoyant members in a horizontaliy or son'iewhat downwardlyextended position when in use.

A further object oi? the invention is to provide a device oi the classdescribed of novel construction and arrangement oi. parts hereinaftermore -fully described, claimed and illustrated in the accompanyingdrawing.

he here embodied my improved device coma pair of buoyant members 10 and11, 35 ct rectangular box shape construction. constructcd p eterably ofheavy waterproof duck canvas or the like. The buoyant members aresecured at their lower form edges to trameworks. consisting oflongitudinal struts 12 and 13 and transverse struts 14 and 15. Thetransverse struts are provided with onion ded portions 16 and 17,respectively hinged at their extremities, as at 18 and 19. respective lyby pins or the like carried in the brackets 26 an d 21. The brackets 20and 21 are secured to the sides of the ship 22, in proximity to thewater line.

A pair of supports comprising; rods and 2a are hinged at one of theirentren'iitics at 25 and 26, by pins or the like, carried in the lugelements 27 and 28 of the transverse menibcrs M and 15, at or near theattended ere tremities of the said transverse members. v The extendedportions 29 and 30 ot the rods .23 and 24; are adapted to slidablyengage in Serial. llo. tit-"L591.

the tubular members 31 and 32, hinged their opposite extremities as atand 3-1 by pins or the like carried in brackets 35 and 36 secured to thesides of the said ship in proximity to the deck thereof.

The above described construction is such as will permit the said buoyantmembers when not inflated to hang vertically downwardly from the sic esof the ship, as designated by the reference numeral 37. i

A. pair of flanged members 38 and 39 are secured to the top positions ofthe said buoyant members, in proximity to the oppo site ends thereof,and are provided with closed ends it) having formed therein a centralaperture adapted to slidably receive the valve stem 4:1, which isprovided with an enlarged head 42 of disc shape construction. normallyheld in a closed position in engagement with the inner surface of theclosed ends of the tian ed members by the expansion sprii on the stem4:1 and retained the) ot the collar is secured to the extremity of thesaid stem. The above described construe tion is such as will p ovide airvalves adapted to permit air pumped through the flexible tubular members15 and ift, secured to the flanged members 38 and 39 to be admitted tothe said buoyant members. as dcsi iated bv the indicating arrows 47, thesaid air t .rcing; the valve open as designated by the rcterence numeral48., so as to pc nit the said air to enter the buoyant members, for thepurpose ct permitting the said buoyant members to be inflated. with airuifider pressure as a means of keeping the said ship ufioat (bariumwhich. or heavy seas, or in event the said ship should founder. lit isobvious that the said buoyant members when inflated will hinge outwardlyfrom the sides oi? the ship.

Collars L9 and are threadedly mounted on the rods 23 and 2 ha. hp;termed thereon at their peripheries, teeth 51 and 52 adapted to meshwith the pinions 53 and 54:, secured to the G1Z" t(l C Cl extremities ofthe rods 54; and 55 re itivcly mounted in the brackets 56, 57. and 59,secured to the tubular membe s 31 and 82. The rods 54 and 55 areprovided wi i enlarged extremities (it) and 61., havi termed th 1 radialapertures G2 and 63 adapted to receive a rod not shown in theaccompauviun" drawing, for the purpose oi manually rotating the rods 54:and 55. The above described construction such as will permit the collars49 and 50, to be i a positioned onthe rods 24 and 25, respective "ly,;soas to securely hold the buoyant mem- "bers when inflated in'ahorizontally or slightly angularlyextendedposition for the sides of thesaid ship, for thepurpose as aboveset forthk r y I The tubular, membersand 46 are extended upwardly from the flange'members and are secured.respectively, to airpumps G4 and 65, respectively secured to the forwardand "aft deck of the ship, or to any suitable convenient part thereof;The said air pumps are of'the ordinary manually operated type. The abovedescribed constructionis such as i will permit air to be pumped-into thesaid buoyant. members for after set forth. i

the purpose as herein- Ihavealso 'sho wn enclosing caps 20, adapted tocover the enlarged extremities 60 and 610i the rods 54Qand 55 andnormally held in engagement over the said'enlarged extremities by.meansof;the expansion springs 71,

'co-axial on the-pin 7 3, and positioned under adapted to preventmoisture particularly 7 from salt water from eorroding the said enlargedextremities and the openings formed therein, which provide capitalv opportunitie's'for such corrosion. The enclosing members. are provided witha flanged edge 75, for

the purposeof'permittingflthe above mentioned bar used torotatethe rods54 and 55, to be used to slidabl'y'open the said enclosing members,renderingaccess to the openings formed therein so as to engage the saidbar, as above set forth, I have also shown a clip 76.secured to andextended from the enclos ing memberfio and adaptedto engage in a notchformed-in the brackets 51, so as to co- '7 act in-thenormally. holdingof the enclosing member in an engaged position Over the said enlargedextremities of the said rods 54 and 55. I Having thus described myinvention what I claim as new and desire to secure by United transversemember for supporting an inflatable buoyant member and arranged forbeing pivotally supported on the side of a ship on its inner edge, a rodpivotally mounted on the transverse member near its outer edge, atubular member engaged on the free end of the rod and arranged for beingpivotally mounted at its outer end on the side of a ship, a collarthreadedly mounted on the said rod and provided with gear teeth on itsperiphery, a pinion meshing with the said gear teeth and fixed on asecond rod rotatively mounted on the tubular member and a means fornormally holding the second rod against rotation.

2. In a device of the class described, a transverse member forsupporting an inflatable buoyant member and arranged for being pivotallysupported on the side of a ship on its inner edge, a rod pivotallymounted on the transverse member near its outer edge, a tubular memberengaged on the free end of the rod and arranged for being pivotallymounted at its outer end on the side of a ship, a collar threadedlymounted on the said rod and provided with gear teeth on its periphery, apinion meshing with the said gear teeth and fixed on a second rodrotatively mounted on the tubular member, and a means for normallyholding the second rod agamst rotation, consisting of an integralenlarged extremity with holes, 011 the said second rod, and a capnormally covering said enlarged extremity.

In testimony whereof I have aflixed my signature.
